COLUMBIA, S.C. (AP) — One of South Carolina's nuclear power reactors remains shut down for what utility executives call a minor, non-nuclear issue.
Federal regulators say the unit automatically shut down Monday morning. It remained offline Thursday morning.
SCANA spokeswoman Rhonda O'Banion says there was a minor issue with the main transformer, and the plant's safety systems responded exactly as designed.
The utility, along with state-owned Santee Cooper, decided last month to abandon construction on two additional reactors at the plant after jointly spending nearly $10 billion.
South Carolina's seven existing reactors supply nearly 60 percent of the state's electricity. The state ranks third nationwide in nuclear energy production.
